Benzothiazines in Synthesis. Further Studies of the Intramolecular, Stereoselective Addition of Sulfonimidoyl Carbanions to α,β-Unsaturated Functional Groups

, 2016
A variety of alkenes substituted by electron-withdrawing groups serve as competent electrophiles for the stereoselective, intramolecular nucleophilic addition of sulfonimidoyl carbanions to form benzothiazines.

Synthesis of 1,2-Benzothiazines by a Rhodium-Catalyzed Domino C–H Activation/Cyclization/Elimination Process from S‑Aryl Sulfoximines and Pyridotriazoles

, 2016
A method for the synthesis of a large number of 1,2-benzothiazines bearing pyridyl as well as carbonyl groups is developed from rhodium-catalyzed carbene insertions into aromatic C–H bonds of S-aryl sulfoximines using pyridotriazoles by denitrogenative ...

Design and Evaluation of Dihydroxytetrahydro-1H-pyrrolo[2,1-c]- [1,4]benzothiazines as Conformationally Restricted Transition-State Inhibitors of β-Ribosidases

, 2016
The preparation of three new chiral thiazines from ribose is described. Two of these are dihydroxytetrahydro-1H-pyrrolo[2,1-c][1,4]benzothiazines with iminopentitol substructures corresponding to the l-lyxo and d-ribo configurations.
